This is mind-boggling. French DJ Madeon creates an entirely new song out of bits of 39 other songs. Oh, and he does it live, playing the samples in off a 64-button Novation Sample Pad. There are bits of Kylie, Jacko, The Yeah Yeah Yeahs and Daft Punk in there... Astonishing work.

Multimedia teen brand Pixie Lott is back with a new single All About Tonight, which roughly translates as *yawn* All About Going To The Club. (I keep meaning to ask - why is there only one club?). This isn't the barnstorming comeback Pixie needed to reinvigorate her see-saw chart career... but it's better than, say, anything Jason Derulo has ever written. And by 'written', I of course mean 'stolen'.

The video is mainly notable for the hilarious legs akimbo dance routine (see above). Pixie Lott has long legs, in case wall-to-wall tabloid coverage had failed to make you aware of this fact.

*6 Music face* Sufjan Stevens is a hugely talented artist given to massive bouts of creativity and self-indulgence. His new album, The Age Of Adz, contains delicate moments of ephemeral beauty and a bunch of songs that waffle on for 10 minutes about absolutely fuck all. This is one of the former - and it comes with a mesmerising stop-motion video, which Sufjan directed all on his own, despite previously suffering a nervous breakdown during Wes Anderson's Fantastic Mr Fox.

Another one of DJ Earworm's semi-annual mash-ups for Capital FM. He's kind of hamstrung by the alarming lack of decent pop music this year, but the juxtaposition of LMFAO and Katy B is sublime.

5) Niki And The Dove - Gentle Roar

Unbelievably, people are still persisting with the whole "[female name] and the [noun]" concept. Latest off the block are Niki And The Dove, a Swedish duo signed to the ultra-hip Subpop label. Subverting the "Alice And The Cheese Grater" subgenre, they make earthy, pagan click-pop, which sounds like Florence Welch swallowing Radiohead. Very classy.
